Universally dispersible particles containing hydrogen bonds

Abstract

The present invention is directed to an entity comprising a particle attached to at least one polymer M through one or several supramolecular interactions -A-B- constituted by 2 to 8 hydrogen bonds X-H-Y, wherein A and B are functional groups respectively grafted to P and M thus forming the particle-containing entity P-(A-B-M)x with x being greater than or equal to 1, functional group(s) B being positioned at one end of the polymeric chain of polymer M, X and Y are heteroatoms present in A and B functional groups, H is hydrogen, and M has a degree of polymerization comprised between 5 and 1000, preferably ranging from 5 to 500. The invention is also directed to a method for preparing this particle-containing entity P-(A-B-M) x , a method for sequentially forming and breaking the supramolecular interactions -A-B- in said particle-containing entity P-(A-B-M) x and dispersions comprising the same.

The invention claimed is: 
     
       1. A particle-containing entity P-(A---B-M) x  wherein P is a solid particle attached to at least one polymer M through supramolecular interactions -A---B- constituted by 2 to 8 hydrogen bonds X—H---Y,
 wherein A and B are functional groups respectively grafted to P and M thus forming the particle-containing entity P-(A---B-M) x  with x being greater than or equal to 1, 
 functional group(s) B being positioned at one end of the polymeric chain of polymer M, 
 X and Y are heteroatoms present in A and B functional groups, H is hydrogen, and 
 M has a degree of polymerization comprised between 5 and 1000, 
 wherein the A-functionalized particles P are attached to more than one polymer M, wherein at least one polymer M is not a biopolymer, and 
 wherein the polymer M further contains between 1 and 5 pending polymerizable groups G.
